@ 2022/12/13Just don’t dowse them with vinegar
Boffins at Princeton University and the University of Washington have developed an ultracompact camera the size of a coarse grain of salt.
The technology uses metasurface, which is studded with 1.6 million cylindrical posts and can be produced much like a computer chip and could find a role looking for problems in the human body and enable sensing for super-small robots.
The new system can produce crisp, full-colour images on par with a conventional compound camera lens 500,000 times larger in volume.
According to Nature Communications the tech involves a joint design of the camera’s hardware and computational processing, the system could enable minimally invasive endoscopy with medical robots to diagnose and treat diseases, and improve imaging for other robots with size and weight constraints.
